The Triangle for Success

I have often used the triangle for success as shown in Figure 1-1 to explain the components needed for a successful project. You need all three facets—a notation, a process, and a tool. You can learn a notation, but if you don't know how to use it (process), you will probably fail. You may have a great process, but if you can't communicate the process (notation), you will probably fail. And lastly, if you cannot document the artifacts of your work (tool), you will probably fail.
